Period induced?

Sarah • Mon, Mar 23 2015 • My husband and I have been together for almost 7 years. Married 08/09/2014 💑 M/C on 03/05/2016 💐 We are ttc for our little rainbow ❤💙💚💛💜💕

My husband and I are ttc #1. Yesterday we had sex and I noticed I was spotting a little afterwards. In the morning, I started having this brown, thick, mucous-like discharge and then I started cramping and had a moderate amount of bleeding. Now I am hardly bleeding at all when usually my periods last from 3-5 days! Should I assume that having sex jumpstarted my period?
